GAS-RADIATOR.

Application filed March 6, 1920. Serial No. 363,766.

To all whom itmag concern.

Be it known that I, Mamus VASSELON,

\ citizen of th Republic of France, residing at 21 Rue Michel Servet, St. Etienne, Loire, in the Republic of France, have invented new and useful Improvements in Gas-Radiators, of which the following is a specification.

This invention relates to a heater or radiator designed in such a manner that it possesses a very large heating surface under a reduced volume. It may be heated by lighting gas, acetylene gas and other gases or a mixture of air with vapors of suitable fuels such as wood spirit, etc.

In the annexed drawing:

Figure 1 a front face of a heater designed in accordance with the invention.

Fi 2 is a vertical cross section of the h same on a smaller scale.

This apparatus comprises several horizon nected by means of hooks, seams, rivets or.

by welding to a sheet metal band suitably bent or curved so as to form the sides (Z and top (Z of the casing.

The walls 0, c are provided with openings to receive the tubes a, the ends of which are flanged externally upon said Walls. These tubes may be made of iron, steel, copper or other suitable metal and arejobtained by drawing out tubes or by means of sheet.

metal blanks which are rolled and welded. Their shape is that of a conic frustum the large base of which is located at the front part of the heater as is clearly shown in Fig. 2. p

The front wall 0 is not extended down to the base part 6 of the apparatus. This base part which is preferably made of cast-iron supports the rear wall 0 and th side walls (Z which are fastened thereto by any suitable means.

A parabolic reflector f is provided at the bottom of the heater underneath the whole series of tubes a and extends along the entire length of the casting e the height of said reflector being somewhat greater than that of the opening 0 between the casting c and the lower edge of the front Wall c.

A burner constituted by a gas pipe 6 provided with holes at its top part extends parallel to the casting c and its position is such that the flames produced occupy the focus of the parabolic surface constituting the reflector so that the radiating effect is completely utilized. This pipeg is supported in the side walls d through which it passes and is provided outside the heater with an extension 6 in which is mounted a Bunsen injector 6 connected to the supply gas pipes by meansof a flexible pipe in the usual manner.

Another wall 0 is provided at the rear of the apparatus at a suitable distance from the wall 0 The metal band forming the side and top walls d and cZ- is sufficiently wide to extend to said wall 0 and close same on three sides thereof, the fourth side being constituted by the casting e, the latter-being however cut out at this part so that the chamber it formed beween the walls 0 c is in communication with the outer air.

The top (Z of the apparatus is provided with a circular opening to receive a pipe j for discharging the spent gases. The pipe j is closed at the top and carries a cylindrical casing 70 having at a suitable point a pipe connection Z leading to the chimney or the outside. The pipe 7' is provided with holes m oppositely located with respect to the pipe Z and opening into the casing 7c.

' The operation of the apparatus is as follows:

The gas burner being lighted, the tubes at will be heated to a hightemperature by the flames of said burner and by the radiation of the reflector. The front and rear walls 0, 0 and the side walls cl will reach also a cer tain temperature. The outer air around the apparatus is thus heated by 1ts contact with the very large heating surface obtained by said apparatus. Moreover the air which is sucked into the chamber it enters into the tubes a through the small end thereof and goes out therefrom through the large end at the front of the apparatus, thus producmg a contlnuous flow of hot a1r as long as the heater 1S 1n use.

Besides, the burnt gases flow upwardly to ward the top of the heater through the pipe It will be noted that on account of the arrangement of the casing with the staggered rows of tubes at and the location of the gas tube 9 the whole volume of the burning gases is obliged to flow around the tubes at which act as baflies in order to reach the outlet pipes j and Z, which avoids every escapement of these gases from the apparatus into the room together with the many drawbacks of the generality of apparatus heretofore used.

The apparatus described yields a much greater heating power than the apparatus now commonly used having the same space and a similar consumption of fuel.

The number of tubes a may be varied as desired as may be the length and diameter thereof according to the heating surface required. The general dimensions may be also varied. In the big sizes, several gas burners 9 may be used instead of a single one.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A gas radiator for heating purposes comprising in combination a base part, a sheet metal casing supported and having its bottom formed by said base member, a plurality of horizontally staggered rows of tubes extending transvers'ally from the front wall to the rear wall of the casing and opened at both ends, an opening in the front part of the casing underneath said tubes, a perforated gas pipe burner supported between the tubes and the base member and adapted to heat the tubes, said burner being connected to the gas supply, a parabolic reflector extending from side to side of the casing at the rear of said opening, and burner, the focus line of which is adapted to coincide with the center line of the flames issuing from the burner, and an outlet at the top of the casing adapted to discharge the spent gases.

2. A gas radiator for heating purposes comprising in combination a base part, a sheet metal casing supported and having its bottom formed by said base member, a plurality of horizontally staggered rows of tubes extending transversally from the front wall to the rear wall of the casing and opened at both ends, said tubes tapering rearward, an opening in the front part of the casing underneath said tubes, a perforated gas pipe burner supported between the tubes and the base member and adapted to heat the tubes, said burner being connected to the gas supply, a parabolic reflector extending supported by the base member, and an air entrance at the bottom of said second casing.

3. A gas radiator for heating purposes comprising in combination a base part, a sheet metal casing supported and having its bottom formed by said base member, a plurality of horizontally staggered rows of tubes extending transversally from the front wall to the rear wall of the casing and opened at both ends, an opening in the front part of the casing underneath said tubes, a perforated gas pipe burner supported between the tubes and the base member and adapted to heat the tubes, said burner beingconnected to the gas supply an outlet pipe having its lower end connected with an opening in thetop wall of the casing, and its upper end closed, lateral openings on one side in the wall of said outlet pipe, a casing surrounding the top part of said outlet pipe into which open the said lateral openings and a pipe connecting a part of the casing opposite to said lateral openings to the point of discharge.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
